Adaptive semi-static interference avoidance in cellular networks

A method of reusing airlink resources in a cellular network, the method comprising:

• receiving sector load information at a base station relating to load levels at adjacent sectors in the cellular network, the sector load information being received from a base station controller;
• generating a reuse pattern based on the sector load information for forward link data transmission in a first sector served by the base station, the reuse pattern comprising at least one carrier or time slot for use in the first sector;
• and
• sending data from the base station to mobile devices in the first sector according to the reuse pattern.

A base station controller, comprising:

• means for receiving information relating to load levels at adjacent sectors in a cellular network;
• means for generating a reuse reference for a first sector in the adjacent sectors based on the load level information, the reuse reference comprising airlink resources designated for forward link data transmission in the first sector;
• and
• means for sending the reuse reference from the base station controller to a first base station serving mobile devices in the first sector.

A base station, comprising:

• means for receiving sector load information from a base station controller for adjacent sectors in a cellular network;
• means for generating a reuse pattern for a first sector served by the base station based on the sector load information, the reuse pattern comprising at least one carrier or time slot for forward link data transmissions;
• and
• means for sending data from the base station to mobile devices in the first sector according to the reuse pattern.

A computer program product comprising:

• a computer readable medium comprising instructions configured to cause a base station controller to:
• receive information relating to load levels at adjacent sectors in a cellular network;
• generate a reuse reference for a first sector in the adjacent sectors based on the load level information, the reuse reference comprising airlink resources designated for forward link data transmission in the first sector;
• and
• send the reuse reference from the base station controller to a first base station serving mobile devices in the first sector.
